Job description

Responsibilities

• Define the target ELT architecture using dbt on Snowflake, integrated with Azure services (ADF, ADLS, Synapse/Databricks, Key Vault, Azure DevOps/GitHub).
• Translate legacy Informatica mappings, workflows, and sessions into modular dbt models (staging, core, mart layers).
• Establish modeling standards (naming conventions, layer design, folder/package structure) for staging, integration, and mart layers.
• Define and implement performance‑optimized patterns in dbt and Snowflake (incremental models, clustering, partitioning logic, query tuning).
• Lead the migration strategy, roadmap, and wave planning for converting Informatica jobs to dbt on Snowflake.
• Analyze existing ETL logic, dependencies, and schedules in Informatica and design equivalent or improved logic in dbt.
• Design a repeatable migration factory: templates, accelerators, mapping spreadsheets, and conversion playbooks for Informatica dbt.
• Oversee conversion, unit testing, and parallel runs to validate that dbt models match legacy outputs (row counts, aggregates, business rules).
• Lead hands‑on development of dbt models, seeds, snapshots, tests, macros, and documentation.
• Define and implement testing strategy using dbt tests (schema tests, data tests, custom tests) and integrate with broader data quality checks.
• Set up and maintain dbt environments (dev/test/prod), profiles, and connections to Snowflake on Azure.
• Introduce and enforce code quality practices.
• Code reviews & pull requests.
• Modular, reusable models and packages.

Requirements

• 8+ years total experience in Data Engineering / ETL / Data Warehousing.
• 3+ years hands‑on experience with dbt (Core or Cloud) building production‑grade pipelines.
• Proven experience leading an Informatica dbt migration to Snowflake on Azure (or similar large‑scale ETL modernization).
• Strong Snowflake experience: designing and developing schemas, views, warehouses, and performance optimization.
• Solid working knowledge of Azure data stack: Azure Data Factory, ADLS, Azure DevOps/GitHub.
